| 11:00 - 12:00 Quantum information biweekly journal club Individual quantum probes for optimal thermometry School NANO SCIENCES Individual Quantum Probes for Optimal Thermometry The unknown temperature of a sample can be estimated with minimal disturbance by putting it in thermal contact with an individual quantum probe. If the interaction time is sufficiently long so that the probe thermalizes, the temperature can be read-out directly from its steady state. Here we prove that the optimal quantum probe, acting as a thermometer with maximal thermal sensitivity, is an effective two-level atom with a maximally degenerate excited state. When the total interaction time is insufficient to produce full thermalization, we optimize the estimation protocol by ... 13:30 - 15:00 Weekly Seminar Unlocking the physics of AGN feedback; IPM galaxy formation model School ASTRONOMY We describe new efforts to model radio AGN in a cosmological context using the SAGE semi-analytic galaxy model. Our new method tracks the physical properties of radio jets in massive galaxies, including the evolution of radio lobes and their impact on the surrounding gas. We now self consistently track the cooling-heating cycle that significantly shapes the life and death of many types of galaxies. Adding jet physics to SAGE adds new physical properties to the model output, which in turn allows us to make more detailed predictions for the AGN population, and build customised AGN-focused mock survey catalogues for comparison with observations. ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Engineering the Wavefunction in Graphene Systems School PHYSICS Farmanieh Seminar Room ... 14:00 - 15:00 Weekly Seminar Engineering the Wave function in Graphene Systems School NANO SCIENCES Engineering the Wave function in Graphene Systems Graphene, a single, atomically-thin layer of graphite, is the most researched material today. Since 2004 - when it was isolated for the first time, ground breaking experiments of fundamental science were followed by a cascade of demonstrations of potential usages of graphene in day-to-day applications. It was in this domain that my research lied: the central theme of my work, "Engineering the Wavefunction in Graphene Systems", was to probe, engineer and harness the very special behaviour of electrons within the graphene sheet (the so-called "Dirac electrons") and by doing so ... |
